JP6418668B2 - Bandwidth allocation for licensed shared access - Google Patents

Description

  The demand for increased data usage and data distribution capacity of communication networks continues to increase as mobile devices such as mobile phones, tablet devices, laptops, etc. become more popular. In order to cope with an increase in bandwidth demand in communication networks, communication network operators and communication network operator providers are configured to use licensed shared access (LSA) bands. Can be used to expand the bandwidth capacity of a communication network. The base station can extend the communication band that can be used by the communication network by using the LSA band together with the licensed communication band and the license-unnecessary communication band of the communication network. The LSA band is usually assigned to an existing operator (primary user) that allows other operators (secondary users) to use the band for communication.

  Access to the LSA band of the primary user by the secondary operator can be used by allowing cooperative sharing access to the LSA band by the existing operator and other operators in order to cope with a shortage of communication bandwidth. Enables more efficient use of Other operators can use the LSA bandwidth as a secondary user to cope with the increase in data traffic on the communication networks of other operators, thereby providing a wider bandwidth that could not be accessed in the past. Can be accessed.

  Reference is now made to the illustrated exemplary embodiment. Certain terminology is also used herein to describe the exemplary embodiments. Nevertheless, it will be understood that these terms are not intended to limit the scope of the invention.

  As will be appreciated by those skilled in the art prior to the disclosure and description of the present invention, the present invention is not limited to the specific structures, process steps, or materials disclosed herein. It should be understood that this also applies to the equivalent. It should also be understood that the terminology used herein is for the purpose of describing particular examples only and is not intended to be limiting. The same reference numbers in different drawings represent the same element. The numbers given to the flowcharts and processes are for the purpose of clarifying the description of each step and operation, and do not necessarily indicate a specific order or sequence.

  In a conventional system, in a communication network such as a cellular network, use and allocation of a band is statically configured based on a part of a license for a communication band from a regulatory agency to a network operator. Static bandwidth allocation to network operators can limit the bandwidth of the communication network for each network operator. In order to increase the bandwidth capacity in the communication network, the network operator and / or the communication network provider uses a base station such as an evolved Node B (eNode B) to increase the bandwidth capacity in the communication network. Such base stations are configured to use a licensed shared access (LSA) band.

  An LSA band is typically allocated to an existing operator (eg, a primary user) that allows one or more other operators (eg, secondary users) to use that LSA band for communication. However, when an LSA band is used by a secondary operator, the LSA band may need to be surrendered when an existing operator requests use of the LSA band. In the conventional method, when an existing operator requests a shared band, it may be difficult for the secondary operator to give up the shared band and return the shared band to the existing operator. For example, if an existing operator suddenly requests a secondary operator to release a wide LSA bandwidth, maintaining the threshold of service (QoS) level and / or bandwidth level is It can be tough for a secondary operator to provide with a significantly reduced possible bandwidth.

  In one configuration, the LSA band may be surrendered by the secondary operator when an existing operator requests the LSA band according to one or more predefined parameters and / or negotiated parameters and conditions. In another configuration, one or more predefined parameters and / or negotiated parameters and conditions may be agreed by an existing operator and a secondary operator. In one example, the parameters and conditions may be fixed parameters and conditions, such as the location and / or time when the band is used by an existing operator. In one embodiment, fixed parameters such as predefined location and / or predefined time can be incorporated into the LSA bandwidth release schedule as discussed in the following paragraphs.

  In another example, the parameters and conditions can be one or more dynamic parameters and / or dynamic conditions. In one embodiment, an existing operator may request LSA bandwidth surrender for emergencies or when bandwidth demand on the existing operator's communications network increases. In one configuration, the LSA band may be used in the European telecommunication standards organization (ETSI) reconfigurable radio system (ETSI RRS).

  In one configuration, the secondary operator and / or the existing operator may be an operator in the communication network. In one embodiment, the communication network can be a cellular network. The cellular network is based on the 3rd Generation Partnership Project (3GPP) long term evolution (LTE) release 8, 9, 10, 11 or 12 standards, and the Institute of Electrical and Electronics Engineers (institute of electrical electronics). and electrical engineers (IEEE)) to operate based on cellular standards such as 802.16p, 802.16n, 802.16m-2011, 802.16h-2010, 802.16j-2009, or 802.16-2009 standards. Can be configured.

  In another embodiment, the communication network is a wireless local area network (eg, a wireless fidelity network) that can be configured to operate using standards such as the IEEE 802.11-2012, IEEE 802.11ac, or IEEE 802.11ad standards. (Wireless fidelity network (Wi-Fi (registered trademark))). In another embodiment, the communication network is Bluetooth®, such as Bluetooth® v1.0, Bluetooth® v2.0, Bluetooth® v3.0, or Bluetooth® 4.0. It can be configured to operate using a trademarked standard. In another embodiment, the communication network is IEEE 802.15.4-2003 (ZigBee® 2003), IEEE 802.15.4-2006 (ZigBee® 2006), or IEEE 802.15.4-2007. It can be configured to operate using a ZigBee (registered trademark) standard such as the (ZigBee (registered trademark) Pro) standard.

  In one configuration, one or more LSA bands defining a procedure for a secondary operator, such as a 3GPP LTE network operator, and an existing operator to release LSA bandwidth from the secondary operator to the existing operator Release parameters can be negotiated. In one embodiment, the secondary operator can release the LSA bandwidth based on the LSA bandwidth release parameter when the secondary operator receives a bandwidth release message from an existing operator. In another embodiment, when a secondary operator receives a bandwidth release message from an existing operator, an evolved Node B (evolved Node B (eNode B)) in the secondary operator's communication network is selected. In order to release the LSA bandwidth over a period of time, an LSA bandwidth release schedule such as an SCell deactivation schedule can be calculated. In another embodiment, the eNode B can communicate the LSA bandwidth release schedule to UEs communicating with the eNode B. In one example, the eNode B can broadcast or unicast the LSA bandwidth release schedule to each UE.

  In one configuration, existing operators and secondary operators can share the LSA bandwidth for a selected period within the bandwidth release period of the LSA bandwidth release schedule. In one example, during the LSA bandwidth release schedule, the allocation of time that a secondary operator can use the LSA bandwidth is a predetermined timetable and / or a timetable by negotiation, eg, from a secondary operator to an existing operator. It may decrease according to the transition of the LSA band.

  In one example, when the existing operator and the secondary operator do not agree on a predetermined timetable and / or negotiated timetable, or when the bandwidth release timetable is shorter than the selected period, The QoS level of UEs in the communication network can be uncertain or unreliable. In another example, when the bandwidth release timetable exceeds the selected time period, the existing operator is in the existing operator's communication network during the selected situation or condition (eg, during an emergency communication situation). There may be no appropriate bandwidth available to the UE. In one embodiment, the predetermined timetable and / or negotiated timetable is a selected time period that allows the secondary operator to maintain a selected quality of service (QoS) level. Can do. In one example, the predetermined timetable and / or the timetable by negotiation can be selected to avoid changes in the LSA bandwidth available to secondary operators that exceed a selected threshold for available LSA bandwidth. One advantage of a predetermined timetable and / or negotiated timetable for releasing LSA bandwidth from a secondary operator to an existing operator avoids a sudden call drop and QoS degradation for the secondary operator's UE. And to secure an LSA bandwidth that can be used by an existing operator when requested.

  In one embodiment, the secondary operator and the existing operator can negotiate and / or renegotiate the LSA bandwidth release timetable or schedule. In one configuration, the LSA bandwidth release schedule is based on LSA bandwidth release parameters, eg, parameters for a secondary operator to release LSA bandwidth when the secondary operator receives a bandwidth release message from an existing operator. Can be.

FIG. 1 shows a timetable of the LSA bandwidth release schedule for the secondary operator 120 to release the LSA bandwidth (LSA spectrum) to the existing operator 110. FIG. 1 further illustrates LSA bandwidth release parameters including: e Node B is a period for fully releasing the selected segment of the LSA band, T _R , which is the start time of the LSA band release schedule, from T _S and T _S to T _R , a periodic time interval distribution rate is updated between the LTE network and the existing network, T _C, and T _C eNode every time interval B is the amount of time to reduce the time shared with the existing network Yes, T _i . In one embodiment, the T _R distribution rate time unit, may be divided into T _C time units of a selected number.

In one example, as shown in block 130, the existing operators, it can be used the LSA band over 1T _I hourly, the secondary carrier, the use of the LSA band over the remaining period of T _C time unit Can do. In another example, as shown in block 140, the existing operators may be used LSA band over 2T _I hourly secondary operators, the LSA band over the remaining period of T _C time unit Can be used. In another example, the amount of time an existing operator can use the LSA bandwidth until the LSA bandwidth is fully released to the existing operator at the end of the LSA bandwidth release schedule (eg, T _R ) is 2 It can increase as the amount of time that the next operator can use the LSA band decreases. In one embodiment, a secondary operator, such as a 3GPP LTE network operator, can use the LSA band as an SCell in conjunction with the primary carrier's primary band using carrier aggregation.

FIG. 2 shows a time frame for releasing LSA bandwidth from a secondary operator to an existing operator over a selected period. In one example, as shown in block 210, the secondary operator's eNode B may receive a bandwidth release message from an existing operator to release the LSA bandwidth to the existing operator. In one embodiment, the bandwidth release message may include a specific time (T _S ) that indicates when the LSA bandwidth release schedule begins. In another example, eNode B may comprise one or more LSA bands release parameter _(e.g., T I, _{T C} and / or _{T R)} evaluates, _T availability changes in LSA band over _R time (e.g., LSA Bandwidth release) can be determined. In another example, as shown in block 220, the eNode B may determine admission control and LSA bandwidth release schedule based on LSA bandwidth release parameters.

In one example, as shown in block 230, the eNode B may send an enhanced broadcast message that includes the deactivation schedule of the SCell on the LSA band to the selected UE in the eNode B cell. In one embodiment, the enhanced broadcast message may include parameters T _S , T _R , T _C , T _I and / or identification information of the SCell to be deactivated. In another embodiment, the eNode B may take one or more steps based on LSA bandwidth release parameters to minimize the impact of releasing the LSA bandwidth on each UE. In one configuration, the one or more steps include: eNode B performs proactive admission control, and one or more UEs use a LSA band to exceed a QoS (Quality of Service) threshold. Limiting the sending of selected types of data using. For example, the eNode B may limit voice calls and / or data transfers that may not be supported at the selected QoS level due to changes in the bandwidth available to the eNode B during the LSA bandwidth release schedule. In another configuration, the one or more steps may be performed by the eNode B in cooperation with the neighboring eNode B in order to cope with a change in available bandwidth for the eNode B during the LSA bandwidth release schedule. To a neighboring UE. In another configuration, the one or more steps may allow the eNode B to adjust the QoS level of voice and / or data communication by the UE, eg, an ongoing call by the UE, through resource scheduling during the LSA bandwidth release schedule. Can be included.

In one example, as shown in block 240, the eNode B and UE may deactivate the SCell based on the LSA band release schedule. In one configuration, the eNode B and the UE can cease data communication with the SCell associated with the LSA band when an existing operator plans to use the LSA band. In another configuration, eNode B and UE may deactivate the SCell on LSA band over a period _{D SC} selected. In another configuration, eNode B and UE may deactivate the 8 subframes of SCell before the start of the next _{T C.} In one embodiment, the eNode B and UE may deactivate the SCell for 8 milliseconds (ms), each subframe being 1 millisecond. In another embodiment, deactivation of the SCell can take digital code D _SC is to deactivate exert full effect. In another example, as shown in block 250, at the end of the _{T R} period, eNode B, it may send a radio resource control (radio resource control (RRC)) command to the UE to release the SCell. In one embodiment, when the UE releases the SCell based on the RRC command, the LSA band is fully released to the existing operator. In one example, when the LSA band is fully released to an existing operator, the eNode B and UE are not on the LSA band but on the primary cell (primary cell (PCell)) associated with the secondary operator. Data communication can be continued

In one example, as shown in block 260, once the eNode B and UE have fully released the LSA band, existing operators can begin to fully use the LSA band. In another example, an existing operator can fully use the LSA bandwidth over a selected number of periods T _I , eg, kT _I. In one embodiment, k is 1 or greater (eg, k ≧ 1). In another example, as shown in block 270, when the period kT _I expires, the eNode B and the eNode B UE may reactivate the SCell. In one embodiment, the secondary operator and the existing operator can renegotiate LSA bandwidth release parameters before the eNode B and UE reactivate the SCell. In another embodiment, the eNode B and UE may reactivate a different SCell from the SCell that the eNode B and UE previously used. In another embodiment, the eNode B and UE may reactivate a different amount of SCell than the SCell that eNode B and UE previously used. In another example, as shown in block 280, when the eNode B and the UE reactivate the SCell, the existing operator can stop using at least a portion of the LSA band.

  FIG. 3 shows an enhanced broadcast message 300 for indicating a schedule for deactivating one or more SCells in a communication network. FIG. 3 further shows that the extended broadcast message can include a SCell-deactivation-schedule-list field in the systemInformationBlockType2 information element. In one embodiment, the SCell-deactivation-schedule-list field of the systemInformationBlockType2 information element is bold.

  One advantage of using the LSA bandwidth release schedule is that the secondary operator releases or returns the LSA bandwidth to the existing operator over a gradual period, thereby allowing the existing operator and the secondary operator to And at the same time minimizing the impact on data transfer by the secondary operator while the secondary operator is using the LSA bandwidth.
